Penerapan jQuery Scroll to Top Control

Dulu saya pernah membahas bagaimana cara membuat "Back To Top" dengan methode yang saya dapatkan dari www.dynamicdrive.com. Adapun penyimpanan file scrolltopcontrol-1.js di www.geocities.com, mengingat sekarang situs tersebut sudah tidak melayani upload gratis dan saya juga tidak punya dollar untuk membayar sewanya maka saya harus mencari solusi bagaimana penerapan jQuery Scroll to Top Control pada Blogger tetap berfungsi. Mengingat penerapan kode ini telah aku terapkan pada blogku yang lain, jadi saya harus berusaha bagaimana kode tersebut tetap berjalan mulus sehingga saya tidak perlu membuangnya.
Seperti biasanya pengeditan kode ini berada pada "Tata Letak" langsung menuju pada edit HTML. Tanpa mencentang "Expand widget templates" tambahkan kode dibawah ini diatas kode </ head>

Jika anda mempunyai variasi dari Icon "Back To Top", silahkan ganti URL img yang ada pada kode dibawah ini dengan URL anda.

controlHTML: '<img src="http://i288.photobucket.com/albums/ll179/ahnning/up.png"

Jika penerapan kode belum berhasil, cobalah ENCODE kode tersebut diatas.
